MORTAR-BED.

SPECIFICATION formingpart of Letters Patent No. 703,344, dated June24,1902. Application filed October 19,1901. Serial No. 79,229. (Nomodel.)

To coll-whom, it may concern:

Be it known that 1, JOHN MARTIN HoLLo- WAY, a citizen of the UnitedStates, residing at Santa Barbara, in the county ofSanta Barbara andState of California, have invented a new and useful Mortar-Bed, of whichthe following is a specification.

This invention relates to mortar-beds upon which mortar in largequantities is mixed; and the object thereof is to provide a portableknockdown device which is arranged to be conveniently set up whendesired for use and as readily taken apart and packed into small compassfor transportation and storage.

It is furthermore designed to obviate the use of nails and the like andto provide for clamping the several parts of the device in such manneras to hold thesame assembled in a strong and durable manner to obviateleakage of the device.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanyin g drawing's,and particularlypoin ted out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a mortar-bedconstructed and ar ranged in accordance with the present invention. Fig.2 is a longitudinal sectional view thereof. Fig. 3 is an end view. Fig.t is a cross-sectional view taken on the line 4 l of Fig. 2.

Like characters of reference designate corresponding parts in all thefigures of the drawings.

In carrying out the present invention there is provided a plurality ofsills or beams 1, shown in the accompanying drawings as three in number;but it will of course be understood that any preferred or requirednumber may be employed. These beams orsills are placed in parallelrelation upon the ground and at suitable intervals, so as to form a baseor foundation for the floor or platform boards 2, which are placedtransversely, the cracks or spaces between the boards being filled withsuitable packing-strips 3, of felt or other material,'so as to provide awater-tight structure, and thereby prevent leakage of the device. Asindicated in Figs. 3 and 4, it will be seen that -thesillbeams 1 are ofsuch a lengthas to project laterally at opposite ends beyond the bottomboards 2, so as to permit of the longitudinal side boards 4 being stoodedgewise upon the projected ends of the sills and flat against theopposite edges of the bottom of the device. The end boards 5 are fittedsnugly between the opposite side boards 4; and are inclined inwardly anddownwardly and have their top and bottom edges correspondingly beveled,so as to lie flush-with the upper'edges of the side boardsand to restfiat'against the bottom of the device. For holding all of the boards ina snug embrace each end of the device is provided with a clamp,comprising a substantially L-shaped body 6, formed by a metal rod whichis bent adjacent to one end so as to form a comparatively longhorizontal mem ber to lie transversely across the under side of thebottom of the device anda shorter upstanding member to lie against theouter face of the adjacent side board. The upper end of the upstandingmember is bowed outwardly, as indicated at 7, so as to form a hook, andwith this book there is engaged an eye-rod 8, which lies transverselyacross the upper edges of the opposite side boards and the adjacent endboard. The corresponding ends of the clamp 6 and the eye-rod 8 projectat one side of the device and pierce a perforate tie-plate 9, said endsalso being screwthreaded for the reception of nuts 10, whereby the clampmaybe caused to tightly embrace the end'of the mortar bed, and therebyhold the parts thereof in a snug embrace. It is preferable to have thebar or rod 8 lie across the upper edge of the adjacent end board, so asto protect the same by receiving such knocks and blows as wouldotherwise displace the board. It will here be noted that the eye of therod 8 may be readily engaged with the book 7, so as to form a pivotal orhinged connection therewith to permit of the rod being swung in planesat substantially right angles to each other, thereby to screw-threadedand passed through an opening in a clip or bracket 12,whicl1 is providedat its upper end with an inwardly-directed lug or shoulder 13 to snuglyembrace the upper edge of the adjacent side board, and a nut 14 isfitted to the projected end of the clamp 11, so as to draw the same intosnug engagement with the device. These intermediate clamps or braces arearranged in alternation, or, in

other words, the clips or brackets thereof are disposed at oppositesides of the device.

From the foregoing description it is apparent that the present form ofmortar-bed retains all of the advantages of the common or ordinary formof board which is nailed together and always remains in a set-upcondition and also overcomes the disadvantages of the ordinary form ofmortar-bed in that it may be readily taken apart, and therebyconveniently transported and stored, and as it is taken apart when notin use it is not liable to become warped. Furthermore, the additionalexpense is very slight and includes only the end and intermediateclamps.

It is preferable to have the end boards inclined inwardly anddownwardly, so as to form obtuse angles with the bottom of the device,and thereby facilitate the use of shovels in removing the mortar fromthe bed.

What I claim is 1. A portable mortar-bed, comprising sills, a bottom andseparate side pieces supported upon the sills, end pieces fitted betweenthe side pieces and inclined inwardly and downwardly in oppositedirections, and clamps embracing the bottom and side pieces.

2. A portable mortar-bed, comprisingabottom, sills supporting the bottomand projected at opposite sides thereof, side pieces supported upon thecorresponding projected ends of the sills, end pieces held between theside pieces, and clamps embracing the bottom and the opposite sidepieces.

3. A portable mortar-bed, comprising a bottom, opposite side pieces, endpieces held between the side pieces and inclined inwardly and downwardlyin opposite directions, and clamps embracing the bottom and the sidepieces, the upper portions of the clamps extending across the upperedges of the end pieces to protect the same against displacement.

4. A portable mortar-bed comprising a bottom, opposite side pieces, endpieces held between the side pieces, and clamps embracing the bottom andside pieces, each clamp having a substantially L-shaped member toembrace the bottom and one side of the bed, an

eye-rod having its eye detachably engaged with the upper end of themember, and a tieplate connecting the other corresponding ends of themember and the rod.

5. A portable mortar-bed, comprising a bottom, opposite side pieces, endpieces held between the side pieces, and end clamps embracing the bottomand side pieces,each clamp having a substantially L-shaped member toembrace one side and the bottom of the bed, the lower end of the rodbeing screw-threaded and projected beyond the opposite side of thedevice, and the upper end of the memher being projected above theadjacent side piece and formed into a hook, an eye-rod having its eyeengaged with the hook and its intermediate portion lying longitudinallyacross the upper edge of the adjacent end piece, the free end of the rodbeing screw-threaded and projected beyond the side of the device, atieplate connecting the screw-threaded ends of the L-shaped member andthe eye-rod, and nuts fitted to the threaded ends of said memher androd.

6. A portable mortar-bed, comprising abot tom, opposite side pieces, endpieces held between the side pieces, clamps embracing the top and bottomof the opposite ends of the bed, and intermediate clamps embracing thebottom and opposite sides only of the device, the intermediate portionof the bed being unobstructed by the clamps.

7. In a portable mortar-bed, the combination with a bottom, oppositeside pieces, and end pieces held between the side pieces, of oppositeterminal clamps embracing the bottom and side boards, and anintermediate clamp, comprising a substantially L-shaped member toembrace the bottom and one side piece, and a clip having a lateralshoulder to embrace the upper edge of the opposite side, the L-shapedmember having its lower part removably connected to the clip.

8. In a mortar-bed, the combination with supporting-sills, of bottomboards supported transversely thereon, the ends of the sills beingprojected beyond the opposite sides of the bottom, opposite side boardssupported upon the projected ends of the sills and rising above thebottom boards, opposite end pieces held between the side pieces,opposite terminal clamps comprising L-shaped members to embrace thebottom and one side piece and having its upper end projected above thebed and provided with a hook, the opposite end of the member beingscrew-threaded and projected at the opposite side of the bed, an eye-rodhaving its eye engaged with the hook and its intermediate portion lyingacross the upper edge of the adjacent end piece, the free end of the rodbeing screw-threaded, a tieplate having openings receiving thescrewthreaded ends of the L-shaped member and the eye-rod, nuts fittedto said screw-threaded ends, and an intermediate clamp comprising anL-shaped member embracing one side piece and the bottom of the device,and an inverted In testimony that I claim the foregoing as substantiallyL-shaped clip embracing the my ownI have hereto affixed my signature inupper edge of the opposite side piece and prothe presence of twowitnesses.
